Introduction

Siag is an X-based spreadsheet for Unix. It uses Scheme (a Lisp dialect) both for expressions and as an extension language, which makes it easy to create new functions (for native Lispers, that is). There is no requirement to know Scheme to use Siag, expressions can be entered in traditional spreadsheet syntax as well.

Siag stands for Scheme In A Grid. It is copyrighted by me, Ulric Eriksson, but is free for use by anybody without paying me any money. Read the file COPYING for more information. The latest version is 2.65.

Siag is distributed in parts, of which only the first is absolutely necessary. The rest can be left out at the cost of reduced functionality.

These are not the original versions of anything. I have modified the sources to give the programs a more uniform look. It works for me.
